Nish, your posts have always set high standards for other bloggers and I have always been in awe of your pics. But I am afraid that this picture disappoints me. I cannot pinpoint any particular aspect but to me this picture does not say anything. I hope you will take my comments in the righ spirit.

A 1/2 stop underexposure would've brought in something from the washed off sky and enhanced the shadows in the picture.

If you had chosen to take this picture with a train that had passengers peeping through windows.... that would've changed all the opinions you have here...

Usage of a bigger aperture too would've done remarkably... the blurring off of the goods train and focussing on the detail of your doorway OR focussing on the other train with the complete blurring off of yoru doorway...would've been other composition choices! :) All the very best.
